HOSE-COUPLING.

b all whom it may concern:

Be it known that I, ALBERT W. ABRAHAM, a citizen of the United States,residing at Oshkosh, in the county of VVinnebago and State of'Wisconsin, have invented certain new and useful Improvements inHose-Couplers, of which the following is a specification, referencebeing had to the accompanying drawings. 7

This invention relates to improvements in hose coupling devices of thatclass which permit two sections of a hose pipe or the like to be quicklyconnected or disconnected.

The object of the invention is to provide a coupling of this characterwhich will be simple, strong and durable in construction, which Willpermit the parts to be quickly and easily connected or disconnected, andwhich will permit the parts to be adjusted to compensate for wear and toinsure a fluid tight joint at the coupling.

With the above and other objectsin view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a side elevation showing theimproved hose coupler; Fig. 2 is a plan View of the coupling showing itsmembers detached; Fig. 3 is a longitudinal section taken on the planeindicated by the line 3-3 in Fig. 2; and Figs. 1 and 5 are detailtransverse sections taken on the planes indicated by the lines 4L4 and5-5 in Fig.

In the drawings 1 and 2 denote the two members or sections of the hosecoupling, the inner ends of which have a suitable telescoping orinterlocking connection which may be as indicated at 3 or of other formand construction and the outer ends of which are adapted to be suitablyconnected to the ends of two pipes, hose sections, or the like. Providedat diametrically opposite points on the outside of the member 2 areoutwardly projecting pins 1 on the opposite sides of each of which arespaced guide and retaining studs 5. The pins 4 provide keepers to beengaged by co-acting connecting devices, hereinafter explained, carriedby the member 1 and the studs or lugs 5 are adapted to retain saidconnecting devices on the keepers.

Provided at diametrically opposite points upon the outside of the member1 are lon- Specification of Letters Patent.

gitudinally extending channeled guide members 6 having undercut walls toreceive slides 7. Pivoted in recesses 8 in the latter by means oftransverse pins 9 are longitudinally extending connecting links 10, thefree ends of which are formed with elongated openings or slots 11 toreceive the pins 4 on the member 2, said slotted ends of the links 10being adapted to lie between the spaced studs or lugs 5, which lattertend to pre vent lateral movement of the links. The links 10 are pivotedat 9 to permit their slotted ends to be readily engaged with anddisengaged from the pins 4 and to hold said links in engagement with thelatter, leaf springs 12 are secured at one end upon the slides 7 andtheir free ends bearing against the outer faces of said links, asclearly shown in Fig. 2. Pivoted to the slides 7 by radially projectingpivots 13 are eccentric strap arms 14, the straps of which surroundeccentric bosses 15 on levers 16 which are pivoted at 17 on themember 1. Said levers are adapted to swing longitudinally and theeccentric bosses or hubs 15 upon them are so disposed that when they areswung longitudinally of the members and over the links 1, they tend. todraw the links inwardly for the purpose of drawing the member 2 towardthe memher 1. The intermediate portions of the levers 16 are providedwith lateral offsets 18 to prevent them from contacting with the slides7 and their free ends are provided with inwardly bent portionsterminating in cams 19 which frictionally engage the member 2 atopposite points to retain said levers in locked position. The resiliencyof the levers 16, together with the provision of the .cams 19 at theirfree ends, insures the retention of the levers in locked position, butit will be understood that if desired, any other locking means may beprovided for said levers. For instance, a recess or seat 19 may beprovided in the member 2 to receive the bent or cam-shaped end 19 of thelever 18 and retain it in locked position. For the purposeof preventingthe levers 16 from being swung over from one side to the other of thedevice, a stop lug 5 is provided upon each of the links 10 forengagement by said levers, as will be readily understood upon referenceto the drawings. To permit of the adjustment of the parts to compensatefor wear on the members 1, 2 and particularly at the joint or connection3, the .eccentricstrap arms 14 are made longitudinally adjustable orextensible by forming each of them in two sections, namely, a tubularsection 20 on which is swiveled, as shown at 21, a rotatable nut 22 forthe reception of the screw threaded end of the other section 23, asclearly shown in Fig. 3 of the drawings. It will be seen that when thenut 22 is rotated the two sections 20, 23 of the eccentric strap armwill be moved into or out of each other and that by varying the lengthof said arms 14: the connecting links 10 may be caused to draw the twocoupling members 1, 2 together to secure an etlective contact at thejoint when'the levers 16 are in locked position.

From the foregoing it will be seen that the invention provides anexceedingly simple and practical device of this character which willpermit two members or sections of a. hose piece or the like to bequickly and easily connected or disconnected, and that the adjustment ofthe parts enables an effective joint to be maintained between the twomembers even after they have become considerably worn.

Having thus described the invention what is claimed is:

1. A hose coupler comprising two members, keeper pins upon one member,the last mentioned member being also formed with recesses, undercutguides upon the other member, slides engaged with said guides, springpressed links pivoted in said slides, and having apertured outer endsfor engagement with said keeper pins, levers having eccentrics,eccentric strap arms between said eccentrics and said slides, andtransverse cams upon the extremities of said levers and adapted to swingover into the recesses in said member.

2. A hose coupler comprising two members, keepers upon one member,slides upon the other member, links carried by aid slides for engagementwith said keepers, levers having eccentrics, and two part eccentricstrap arms between said eccentrics and said slides, the parts of saideccentric strap arms having a screw threaded engagement whereby saidarms may be varied in length.

3. A hose coupling comprising two members, keepers upon one member,slides upon the other member, links carried by said slides forengagement with said keepers, levers having eccentrics andlongitudinally adjustable eccentric strap arms between said eccentricsand said slides.

4. A hose coupling comprising two mem bers, keepers upon one member,slides upon the other member, links carried by said slides forengagement with said keepers, levers provided with eccentrics, eccentricstrap arms between said eccentrics and said slides and arms upon saidlevers for retaining them in locked position.

5. A hose coupling comprising two members, keepers upon one member,slides upon the other member, links carried by said slides forengagement with said keepers, levers provided with eccentrics, eccentricstrap arms between said eccentrics and slides, stops upon said links tolimit the swinging movement of said levers, and co-actingmc-.1ns uponone of the members and said levers for retaining the latter in lockedposition.

In testimony whereof I hereunto aiiix my signature in the presence oftwo witnesses.

ALBERT \V. ABRAHAM.
